Definitions

  • the present invention relates to a sealing tape with at least one base body made of soft foam that is resilient after compression.
  • Sealing tapes are generally used to seal joints between components, in particular frame profiles of windows or doors, and the building wall.
  • the sealing tape comprises a foam carrier in which incisions are made alternately from the upper side and from the lower side.
  • a film strip, an adhesive tape strip or an adhesive-like medium is inserted into each of these incisions in order to form a barrier layer which extends over part of the height between the upper and lower sides of the sealing tape.
  • a portion of each barrier is also disposed on the respective top and bottom, respectively.
  • air ducts and / or water vapor diffusion ducts can form between the sealing tape and the rough surface of the adjacent building wall. It cannot then be guaranteed that the sealing tape will have the desired or intended sealing properties. Due to the multiple incisions of the foam carrier from both sides and the insertion of the barrier layer components into the foam carrier, the production of a sealing tape in this way is also very complex.
  • the present invention is based on the object of providing a sealing tape that is simple and inexpensive to manufacture and whose intended sealing properties are reliably achieved.
  • the sealing tape comprises at least one base body made of soft foam that is resilient after compression, the sealing tape having a top, a bottom and a first and a second side flank that connect the top and the bottom, the side flanks being essentially perpendicular to a functional direction of the sealing tape.
  • the sealing tape has a continuous blocking structure for reducing the water vapor diffusion permeability and / or the air permeability in the functional direction, the blocking structure extending from the top of the sealing tape to an underside of the at least one base body.
  • the blocking structure also extends over a region of the upper side of the sealing tape and, at least there, has closed-cell foam or is formed from this. At least in the area of the upper side of the sealing tape, the barrier structure has a thickness between 10 ⁇ m and 5 mm.
  • the barrier structure comprises a closed-cell foam at least on the upper side of the sealing tape offers the advantage that the soft foam is particularly elastic against the building wall, thus avoiding the formation of air channels and / or water vapor diffusion channels between the sealing tape and the building wall in the functional direction.
  • the sealing properties of the sealing tape can be adjusted in a targeted manner with regard to the water vapor diffusion permeability and / or air permeability of the sealing tape. In this way, the functionality of the sealing tape is expanded.
  • the barrier structure can, for example, be laminated or laminated to the at least one base body, as is known to the person skilled in the art for connecting two bodies comprising foam.
  • the suitability of the barrier structure for contacting the wall as tightly as possible and for improving the sealing effect of the sealing tape is influenced by the material properties of the barrier structure.
  • the closed-cell foam of the barrier structure is therefore formed in a preferred embodiment from polyurethane, polyethylene, polyvinyl chloride, polyolefin or polypropylene and has a density of between 15 and 200 kg / m 3 .
  • the closed-cell foam of the barrier structure preferably has a compressive strength between 2 kPa and 15 kPa, preferably between 2.1 kPa and 10 kPa, more preferably between 2.2 kPa and 5 kPa based on a compression of 40% compared to the initial height (CV40) DIN EN ISO 3386: 2015.
  • closed-cell foam is understood to be a flexible foam that has an increased number of closed cells or cells with only a small opening cross-section.
  • the closed-cell foam is characterized solely by its air permeability.
  • the air permeability of a closed-cell foam is at most 50 l / (m 2 s), or more preferably at most 40 l / (m 2 s), or more preferably at most 30 l / (m 2 s), or more preferably at a maximum of 20 l / (m 2 s), measured according to DIN EN ISO 9237: 1995; Test area 100 cm 2 at a measuring pressure (negative pressure) of 1.0 mbar, test device Frank 21443.
  • the barrier structure preferably also has a thickness between 15 ⁇ m and 3 mm, preferably between 50 ⁇ m and 2 mm, at least in the area of the upper side of the sealing tape.
  • the blocking structure extends completely between an upper side of the at least one base body and an underside of the at least one base body in order to effect the desired seal over the entire cross section of the at least one foam base body.
  • the at least one base body is oriented like the sealing tape, ie the top of the at least one base body is arranged in the area of the top of the sealing tape and preferably extends parallel to it and the underside of the at least one base body is arranged in the area of the underside of the sealing tape and preferably extends parallel to this. If no further components of the sealing band are arranged on the upper side or the lower side of the at least one base body, these at the same time form the upper side or lower side of the sealing band.
  • further components of the sealing tape are arranged on the top or the bottom of the at least one base body, such as a barrier layer or an adhesive layer, so the surface of this component facing away from the other components in each case forms the top or bottom of the sealing tape in this area.

  • the blocking structure preferably extends along the upper side up to an area between the first and the second side flank and runs there from the upper side in the direction of the lower side of the sealing tape. Sensitive parts of the barrier structure are thereby protected from damage by external influences during transport or handling, since the one running from the top in the direction of the bottom on both sides Section parts of the at least one base body made of soft foam are arranged.
